Hunter's comment
The NSD Spinner is a gryoscope for the hand that aims to build strength in the hands, wrists and forearms.
There are two types of NSD Spinners:
- Manual Pull String Spinner
- Autostart Version
With the manual pull string spinner, pull the string which starts the motor in the spinner. Once the motor is active, grip the spinner and rotate your wrist around. As you rotate and grip the spinner, the spinner gets faster and faster.
The autostart version does not require pulling on the string to get the motor started.
Although it is more expensive consider the NSD spinner with the autostart feature over the manual pull string version.
